Question

how is the small intestine designed to assimilate the food /Explain.

Answer 1

Answer:

To digest the carbohydrates, fats and proteins, the small intestine receives the secretions of the liver and pancrease. The acidic food coming from the stomach is made alkaline for the action of pancreatic enzymes. The liver secretions have bile juice. The bile salts break the larger fat globules into the smaller one for the effective action of enzymes (emulsification of fats).

The walls of small intestine contain glands that secrete intestinal juice. This contains enzymes to convert:

• Proteins àamino acids
• Complex Carbohydrates àglucose
• Fats àfatly acids & glycerol
• The digested food components are absorbed into the walls of the intestine.

Answer 2

Answer:

The small intestine has millions of tiny finger-like projections called villi. These villi increase the surface area for more efficient food absorption. Within these villi, many blood vessels are present that absorb the digested food and carry it to the bloodstream.
